Let's get to that breaking news now.
That's where we start tonight at six.
We now know the name of the suspect
in the West Bend death investigation we've been reporting.
Police just officially releasing his name just moments ago.
Our Durante Matthews in West Bend with the latest.
And Durante, we found out some information last night,
the two of us, and now we can officially report that.
Exactly, Mary. So just a couple of minutes ago, West Bend
police identified the suspect as 54 year old David Slonikowski.
Now, multiple police sources too actually yesterday.
Confirmed to us that Slonikowski is a former Milwaukee police officer.
They tell us he retired more than a decade ago
and his retirement was not duty related.
Now, police also tell us out of respect for the victims in this case,
they will not be releasing the names of the other three.
But West Bend police say this all started on Saturday morning
just before noon when they got a 911 call that alerted them
to this home here near Washington and Wisconsin Street.
Inside, they found...
Slonikowski, an adult woman, a boy, a girl, and a dog dead.
There was another girl inside that they took
to the hospital for treatment.
Police say there was a firearm inside that they
do believe was connected to this incident.
Now, today, the Washington County medical examiner told me this morning
they started autopsies on all four people they found inside the home.
All day today, we've seen people coming back and forth to this home,
some by themselves,
some with groups of people.
They've been mourning and grieving the loss together.
They've been leaving flowers as well as stuffed animals and balloons,
even writing their names
on wooden hearts that were left here in front of the home.
Now, yesterday, we caught up with people
who say they knew this family well and tell us
the situation is just beyond heartbreaking.
They were a welcoming family.
Their mom was incredible.
Their children were incredible.
I will forever cherish this family as it was my own.
And that's kind of the same sentiments that we've heard
from other people who have been coming here,
leaving flowers out of respect for this family.
Now, once again, police have identified the suspect
in this incident as 54-year-old David Slonikowski.
Two police sources told us yesterday that he
is a retired Milwaukee police officer.
West Bend police tell us as of right now,
this is the last update they plan to release
on this particular case.
For now, reporting live in West Bend, Durante Matthews, Fox 6 News.
So, Durante, they have not given a motive.
Is there any chatter or any talk from them on a possible motive?
There has been no indication of what the motive may be.
However, on Saturday, police gave a press conference,
and at the end of that press conference, they cited sources for people
who may be experiencing domestic violence.
So that is the closest indication
that we have gotten to a possible motive.
All right. Durante Matthews reporting live there
in West Bend. Thank you for the update.
